Safety instructions

These Operating Instructions contain information which you should observe to ensure your own personal safety as well as to protect the product and connected equipment. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol. Notices referring only to equipment damage have no safety alert symbol. Warnings are shown in descending order according to the degree of danger as follows.

DANGER

indicates that death or serious injury will result if proper precautions are not taken.

WARNING

indicates that death or serious physical injury may result if proper precautions are not taken.

CAUTION

with a safety alert symbol indicates that minor personal injury can result if proper precautions are not taken.

CAUTION

without a safety alert symbol indicates that damage to property may result if proper precautions are not taken.

CAUTION

indicates that an unwanted result or state may occur if the relevant instruction is not observed.

In the event of a number of levels of danger prevailing simultaneously, the warning corresponding to the highest level of danger is always used. A warning that uses a safety alert symbol indicating possible personal injury may also include a warning relating to material damage.

Description

2.1 Application

2 Description

2.1 Application

The SINVERT PV inverter is a fully assembled, ready-to-connect inverter unit for PV installations.

1 2 3

Figure 2-1 Overview of PV system

The inverter transforms the DC voltage produced by the PV modules into an AC voltage.

The AC output voltage is transformed to the grid voltage by a medium-voltage transformer.

The PV solar system can thus be connected to the medium-voltage grid.

Hardware operation

3.1 Commissioning the inverter

3 Hardware operation

3.1 Commissioning the inverter

Commissioning an installation requires certain switching operations to be performed. This type of work must always be undertaken by qualified, properly trained personnel. Failure to perform switching operations correctly can result in significant property damage and serious physical injury. The components described in this manual operate at hazardous voltages and currents. Proper precautions must be taken during the commissioning process. This manual describes only the manual process of switching the PV system on and off. The system must be switched on and off manually in order to carry out performance tests and maintenance procedures.

3.1.1 Instructions and safety information

In accordance with the relevant standards and legislation (e.g. DIN VDE 0105), properly trained specialists must always be employed to operate and control electrical equipment. All employees authorized to undertake switching tasks must receive instruction in accordance with the relevant standards and legislation (in Germany, at least once annually in accordance with BGV A1 §4 (Institute for Statutory Accident Insurance and Prevention/Instruction of Insured Persons)). Follow all safety guidelines and work instructions stipulated by the relevant legislation and standards. Never take any action which would endanger either yourself or others.

The five safety rules in Germany:

1. Isolate from power supply

2. Provide a safeguard to prevent unintentional reclosing

3. Make sure that the equipment is de-energized

4. Ground and short

5. Cover or place guards around adjacent live parts

CAUTION

The instructions and guidelines relating to operation and control of the installation contained in the operating manuals for the switching equipment and other devices described here must be adhered to.

CAUTION

The safety rules (for example, DIN VDE 0105 – 100 § 6.2 in Germany) are especially applicable to switching or voltage disconnection operations.

If you are working abroad, you must adhere to the relevant local safety rules. Always pay particular care and attention when working on or around electrical equipment.

Hardware operation

3.1 Commissioning the inverter

3.1.2 Switching off and disconnecting the power supply

The entire system must be disconnected from the power supply before test and maintenance work can be carried out in the containers. Carry out these tasks in the sequence given below:

1. Press the OFF key briefly on the control panel of every inverter.

2. For reasons of safety, also press the Fast Stop button (if one is installed) in the inverter room.

3. Disconnect the external power supply (most commonly in the AC distribution cabinet) by opening the fuse switch disconnector or by switching off the miniature circuit breaker.

4. Open the AC-side and DC-side fuse switch disconnectors in all inverters and remove the fuses, including the fuse holder, or remove the fuse cartridge with a fuse tong. This means that the inverter cannot be switched on again (remember the five safety rules).

DANGER

The AC and DC connections are still live externally!

5. In order to disconnect the AC end completely from the power supply, the relevant medium-voltage transformer must be switched off at the medium-voltage switchgear. After switching off, open the medium-voltage isolator and close the medium-voltage grounding switch. The machine switching operations on the medium-voltage components must be performed via the power supply company or an authorized person.

6. In order to disconnect the DC end completely from the power supply, all relevant junction boxes of the generator and coupling boxes (if installed) must be disconnected. The disconnectors in the generator junction boxes and/or coupling boxes (if installed) can be switched under load. In contrast, fuse switch disconnectors must not be switched under load. Likewise, fuse cartridges in fuse holders must not be removed under load.

DANGER

Fuse switch disconnectors in the inverters and junction boxes must not be switched under load! Do not remove fuse cartridges when they are under load!

Hardware operation

3.1 Commissioning the inverter

3.1.3 Switching on

The inverter is switched on in the same way as it is switched off, but in the reverse sequence.

1. Check that all connections have been made correctly (including polarity).

2. Switch on the junction boxes in the PV field.

3. Switch on the external power supply for the medium-voltage switchgear.

4. Switch on the external power supply for the inverter container.

5. Close the medium-voltage breaker.

o Open the grounding switch. o Close the switch disconnector. o Close the circuit breaker. o Note: Depending on the type of MV switchgear installed, the step sequence might vary.

6. Close the DC fuse switch disconnectors in all inverters.

7. Close the AC fuse switch disconnectors in all inverters.

8. Unlock the "Fast Stop" button.

9. Turn the keyswitch on all inverters from "Auto" to "Test" and back to "Auto" in order to reset settings.

10. If insolation levels are sufficiently high, the system will restart automatically after 30 minutes.

11. To start the system immediately, you must turn the keyswitch on the master to the test position. Then press the internal key "S111".

12. The DC contactors are automatically closed one after the other. The inverter is then started and the AC contactor is immediately closed. Now turn the keyswitch to "Auto".
